Overclock.net has been abuzz in recent days with a couple user-modded BIOS files that have brought success to many users in eliminating throttling with their Titans, as well as spectacular on-air overclocks!

USE AT YOUR OWN RISK!

I thought it would make things easier for folks if I aggregated the info you need to flash here…no support or help or warranty is implied, again: USE AT YOUR OWN RISK! Head over to the original Overclock.net thread here if you have questions or comments.

2) FLASH BIOS FILEFlash with NVFlash [453 KB], this version works in 64-bit Windows. Instructions on how to flash below, from this original source.

Download that and extract it into a folder, in that folder also make sure you have your modded bios, for reference I will be calling it “X.rom” you can rename it to that to keep this more simple..

Shift+ Right click in the folder and click “open command window in here” then type the following commands in order.

Nvflash – -protectoff

Nvflash -4 -5 -6 X.rom

If you want to flash multiple GPUs (i.e. SLI) – use this post, or view here:

nvflash – -list to know each card index number
nvflash -version -i1 to know the bios version (and some other info) of card number 1
nvflash – -save -i1 gtxtitan_1.rom to save original titan bios of card 1 to file
nvflash -version -i2 to know the bios version (and some other info) of card number 2
nvflash – -save -i2 gtxtitan_2.rom to save original titan bios of card 2 to file

What tool did yo use to modify the bios to 1.25v ? Because the keplerbiostweaker doesn’t allow this adjustment and the already uploaded bios gives me black screen on all 3 of my titans so have reversed to orginal with modified powerlimit to 150%. They are running on water so high voltage would be nice.
